Elf Ear Filler: Shaping Flat Ears for a Smaller-Looking Face

I'm Dr. Jong Seon Kim, a director at Gangnam HERA in Seoul. I'm a board member of the Korean Society of Aesthetic Surgery and of the International Petit Medical Society. In this video I explain a treatment that has become popular in Korea as interest in facial contour has grown: ear filler. More people want a smaller-looking face and a clearer outline through a procedure rather than surgery, and the ears turn out to be one of the simplest places to do that.

My short answer: ear filler can bring flat ears forward and round a sharp ear rim in around 5–10 minutes, which makes the middle of the face look narrower. Done well, it takes much less filler than older methods — at HERA no more than about 1–2 mL behind the ear.

What kinds of ears does ear filler treat?

Mainly two: flat, pinned-back ears and sharp, "knife-edge" ears. A normal ear opens away from the head at roughly 15 to 30 degrees. Some ears sit folded back so far that you barely see them from the front. In Korean we call these "lying-down ears". Because the ears disappear, the middle of the face looks wider.

The second type is what Koreans call a "knife ear": instead of a soft, rounded rim, the lower edge looks as if it was cut straight with a knife. Some people are born this way. It can also appear after facelift surgery, when long incisions around the ear pull the scar downward and flatten the ear's rounded curve.

How does ear filler change the shape of the ear?

For flat ears, filler pushes the ear gently forward; for knife-edge ears, it rebuilds a rounded curve. Because there is no surgery, the procedure takes around 5–10 minutes, downtime is small and you can go straight back to normal life. The shape is visible immediately.

Why does ear shape change how wide the face looks?

Because ears that stand slightly forward frame the face, so the mid-face looks narrower and the outline looks sharper. Many East Asian faces are relatively broad in the middle. In the past, when the cheekbones were prominent, the answer was often contouring surgery — cutting bone and enduring a hard recovery. People started asking whether there was a simpler way to make the middle of the face look smaller, and the ears became the key. I like to describe ear filler as non-surgical face contouring.

What is a "goddess ear"?

It is my name for ear filler that shapes the rim, not just the angle. Some K-pop idols are known for ears that stand slightly forward and rise toward the top in an elf-like shape, and many younger patients now ask for that look. Simply pulling a flat ear forward does not create it. Building out the rim and enlarging the upper part does. So the goal goes beyond "un-flattening" the ear: it is to make the outline of the rim attractive. That is what I call the goddess ear.

Why use less filler behind the ear?

Because a large lump of filler behind the ear can hurt, especially when you lie on your side. The first generation of ear filler tried only to stand the ear up, so it relied on a large amount behind the ear. I see patients who arrive with 4–5 mL there — a lump that sits like a dumpling. Many of them complain of pain when they lie on their side.

Our goddess ear filler does not put that much behind the ear: at most around 1–2 mL. Because filler goes exactly where it is needed for the shape, a smaller amount gives an effective result. It is the same principle I explain in why less filler looks better: the minimum amount for the maximum effect, with fewer side effects and less downtime.

What is the aftercare after ear filler?

Keep the dressing on, sleep on your back for two nights and be gentle for about two weeks.

1. Dressing: filler goes in through tiny needle entry points, which we cover with a thin hydrocolloid patch until they close — usually 2–3 days. Take care when washing your face or hair.
2. Sleep: before the shape settles, the ear should not be twisted or pressed, so sleep on your back for two nights.
3. Two weeks of care: avoid pressing or folding the ear — tight hats, headphones that clamp, or sleeping on your side.

Mild swelling or tenderness at the entry points can occur and usually settles within a few days. As with any filler, rarer complications such as infection are possible, and results vary from person to person. For how long to plan your stay, see Korean ear filler: how many days?

Can ear filler be combined with other contour treatments?

Yes, and the combination often looks better than ear filler alone. Ear filler ultimately serves the face outline. If the cheeks are sagging, or there is a lot of fullness in the front cheeks, the new ear shape shows less. In those cases a laser or thread lifting can be added, and for heavy cheeks we have a fat-dissolving injection, Sok-Sok. Combined with contour treatments, the effect is noticeably stronger.

Earlobes are another small but popular area. There is an old Korean saying that full earlobes bring good fortune. I'm not sure whether it's superstition, but not long ago a businessman drove all the way from Busan to Gangnam for earlobe filler, and he left very satisfied. I also cover ears alongside other less-common areas in ear filler and other special-area fillers.

How does ear filler work for international patients at HERA?

It is one of the easiest fillers to fit into a trip. You receive an itemized written estimate naming the product and amount before treatment; international patients pay the same as local patients, and an English interpreter is with you. The treatment itself is short, and most people go back to their plans the same day, keeping the aftercare above in mind.

The honest limits

Ear filler changes how the face is framed; it does not change the bones of the face. If width comes mainly from the jaw or the cheekbones, the effect will be gentler. Very stiff or very folded ears may take more planning, and filler is not permanent. What it offers is the most up-to-date form of ear filler as I see it: shaping the rim to your needs with the least filler, fewer side effects and less downtime.
